Tweakers' Asylum

It's not a sponge, it's a radiator. It produces sound, not absorb it.

Well, if you physically activate the fork, it will certainly radiate 120 Hz. Look at it in the opposite way.

The fork actually wants to be activated at 120 Hz, and is designed to resonate at that frequency. If it is not physically activated and sitting idle, I reckon the tuning fork will try to resonate due to the 120 Hz it is exposed to in the air. Think about how much energy it can absorb trying to fully resonate. That is a pretty big pile of metal, and can sink a lot of energy getting revved up. It would have to be exposed to a lot of intensely radiated 120 Hz to start to audibly resonate. Might be fun to put it in front of a speaker playing 120 Hz, turn up the volume, and see what it takes to get it started - my guess is a whole lot. Certainly not what you should be seeing behind some components in an audio rack....

I was more concerned about the mass of the fork being too great to pay attention to the likely small amount of 120 Hz back there. Ordered one today, so should be able to see what happens in a week or two.

Doesn't Stanley Hammers have a tuning fork in their professional hammers because it absorbs the vibration from the hammer strikes before it enters into the hand/wrist/arm??? I'm not going to just reject it, but hey, for a few $$ for someone serious about this hobby what does one have to lose. It worked, it didn't work.

  Well Charlie, I offered a free titanium screw tweek for ac faceplates and only a few were interested. Couldn't get easier or cheaper than that. I myself got a large improvement in the one system I tried it in.
